20 Claims.

This invention is an improved staple remover and the objects, advantagesand functional and structural features thereof will be better understoodfrom the following detailed description considered in the light of theaccompanying drawing wherein:

Fig. 1 is a side viewof the staple remover according to my invention,illustrating the plunger raised and the rectilinearly displaceableelevator depressed prior to removing a clinched staple.

Fig. 2 is a view similar to Fig. l but showing the slidably guidedplunger depressed and the elevator raised extracting a staple.

Fig. 3 is a fragmentary front View of Fig. 1.

Fig. 7 is a horizontal transverse sectional view on the line 1 1 of Fig.5.

Fig. 8 is a rear elevational view of Fig. 5.

Fig. 9 is a cross sectional view on the line 9 9 of Fig. 8.

Fig. 10 is a cross sectional View on the line IU-I of Fig. 8, and

Fig. 11 is a side view of the support.

The staple remover broadly designated R comprises a support S, areciprocably guided plunger P, a vertically and rectilinearly guidedelevator E and a closure or cap C.

The support S is a channel shaped member having a rear wall I0integrally merged with the forwardly extending and spaced walls I Idefining the opening I2.

Extending forwardly of and integrally with the rear wall I0 but spacedfrom the biased and lower ends I3 of the sides I I of the support S isthe bottom plate or sustaining member I4 having forwardly extending andspaced rectilinear projections or lugs I provided with taperingterminals I6 having the outer sides II converging forwardly and theirouter corners I8 rounded as shown in Fig. 9.

Lugs I5 define a gap I9 for removably receiving the rectilinear staplelifting tongue 20 oiset 2 slidable displacement of the elevator Erelative to the support S the spaced sides II of the latter eachembodies an elongated slot slidably guiding the laterally extending lugs26 integral with and projecting from the wings 23.

Journaled to the spaced sides I I of the U-shaped support S is therotatable shaft carrying pinion 3I in mesh with teeth 32 of the elevatorE and the teeth 33 of the inwardly depressed portion 34 of the plungerP. In eiect it may be said that the pinion 3| is actuated or driven bythe rack dened by the teeth 33 of the plunger P and when so actuated,causes the displacement of the rack dened by teeth 32 of the hollow rib22 of the reciprocable elevator.

The plunger P is a hollow substantially square shaped casing wherein itsfront wall 35 embodies the depressed portion 34 and its side walls 36closely but slidably straddle the spaced sides I I of 20 the support Swhile its rear wall 3'I slidably engages the rear wall I 0 of theSupport S. In other Words, the plunger P telescopically receives a partof the support and, is slidably guided thereon although it is normallyheld in a raised or elevated 25 position by the tapered helicoidalspring 38 havfrom lug 2l extending forwardly of and integral I with thehollow boss or rib 22 of the elevator El Extending laterally of boss 22and integral therewith are the wings 23 slidably retained against therear wall I0 of the support S by the spaced inwardly crimped portions orribs 24 struck into the sides I I. To further insure proper ing an endseated on the top faces 39 and 40 of the spaced sides II and the wall I0of the support. and having its narrower end retained by a cap C anchoredto the plunger by the crimped portion 42. Detents as 43 are bentinwardly from the rear wall I0 and the spaced side walls IIvof thesupport S and serve to prevent slippage of the lower part of the springinto the channel I2 defined by the side walls I I of the support. Toprevent removal of the plunger from the support fastening means in theform of a set screw 44 is fastened to and carried by the rear wall 31 ofthe plunger and this set screw extends into the elongated guide slot 45of the rear wall I0 of the support S.

By the arrangement disclosed, the plunger is normally held raised by thespring 38. In such relation tongue 20 and its tapered terminal 46 arecoplanar with that is, in the same plane as the lugs I5 and the taperedterminals I6 respectively at which time lug 2| of the elevator E isresting on the seat `or sustaining member I4 which embodies the spaceddepressed portions or ribs 41 and 48 adapted to sustain the stapleremover upright when not in use. However, when in yuse of the stapleremover the latter may -be tilted on rib 41 Awhich serves las -fulcrummeans.

Prior to 4withdrawing a staple 50 anchoring sheet material 5I the stapleremover is rocked on the rib 41 as explained above to present the|tervthe rack on said plunger on the displacement of adapted tobeinserted under said bridge and between said legs, an elevator having astaple lifting tongue removably disposed between said lugs and adaptedto be inserted under said bridge, a plunger, means for slidably guidingsaid plunger on said support, means for slidably guiding said Y itaining said lugs and tongue tilted relative to said staple.
